Mick Jagger's fashion designer girlfriend has been found hanging in her New York apartment

To recap, a friend has revealed L'Wren was planning to close her fashion business this week.

American fashion journalist Cathy Horyn said she was going to announce the end of LS Fashion on Wednesday.

Cathy wrote in a piece titled 'Memories of a Friend, a Teacher and a Fighter', in the New York Times newspaper: "I sent her text on March 12, checking in. She didn't reply, but that wasn't unusual.

"I learned since her death that she was planning to close her business, with an announcement on Wednesday. Still, as painful as the decision must have been for her, I wouldn't draw any conclusions from it about her state of mind. Nor should any credence be given to reports of a breakup with Mick. It's rubbish."

The Rolling Stones' private jet is still reportedly on the tarmac at Perth International Airport - despite being packed with gear earlier today.

The band's equipment was loaded on to the 767 jet - but there is still no sign of the men themselves.

The Stones cancelled their entire tour round Australia and New Zealand after L'Wren's death.

They were in the country for their 14 On Fire six-show stadium tour.

Yesterday, a representative from Frontier Touring said reports Jagger has left the country were – “to their knowledge” – wide of the mark, adding the band “has gathered together and they’re dealing with the situation”.

To recap, the latest accounts for L'Wren's business LS Fashion Ltd, filed in the UK in October 2013, showed the firm had a deficit of £3,545,226. Her company also owed creditors £4,591,903.

A pal said: “L’Wren was left terribly upset by what was going wrong with her business, none more so than when she was forced to cancel her London Fashion Week show in February.

“She was a proud woman and understandably embarrassed by what had happened. While Mick was there for her every step of the way trying to help out as best he could, the situation must have put pressure on their relationship.”

The friend added: “She blamed the fashion week debacle on production delays but this was masking the huge financial problems her company had.

“In the cut-throat world of fashion, reputation is everything and it must have been a huge personal blow to pull the show. Her fear of failure in her peers’ eyes may, ultimately, have been too much.”

Following the Stones' announcement that their Australia and New Zealand tour has been cancelled, disappointed fans have taken to Twitter to express their understanding.

"Understandable. we're all here for MickJagger and Lwren Scott's family Condolences" wrote one user.

"Really sorry to hear the sad news for Mick & friends of L Wren," said another.

1:12 pm

L'Wren Scott's older sister Jan Shane believes the late fashion designer was unhappy with her jet-setting life.

They were both adopted and raised by Mormon parents in Utah.

Jan told the Daily Mail newspaper: "To me she had it all. She was going out with a Rolling Stone and travelling to London and all around the world and I was a stay-at-home mum who hasn't really been anywhere."

Jan, who has eight children and has been married for most of her life to the local binman, admits it was at her father's funeral in 2002 when she realised all wasn't well in her sister's life.

She explained: "It was hard to get near her. I don't know why she thought she needed bodyguards at our father's funeral. I guess that's just how her life was at the time.

"But at one point we stepped out together and she looked at me and said, 'I envy you.'"

A statement read: "The Rolling Stones are deeply sorry and disappointed to announce the postponement of the rest of their 14 ON FIRE tour of Australia and New Zealand following the death of L'Wren Scott.

"Mick Jagger, Keith Richards, Charlie Watts and Ronnie Wood wish to thank all of their fans for their support at this difficult time and hope that they will fully understand the reason for this announcement.

"The Rolling Stones are planning to reschedule these postponed shows at a later date."

Touching tributes from the Rolling Stones have just been released

Ronnie Wood: "This is such terrible news and right now the important thing is that we are all pulling together to offer Mick our support."

Keith Richards: "No-one saw this coming. Mick's always been my soul brother and we love him. We're all feeling for the man."

Charlie Watts: "Needless to say we are all completely shocked but we have to do what is right in these sad circumstances."

The designer was all smiles as she spoke about the success of her fashion empire last year.

Scott, who was 49 when she died, posed alongside long-term lover Mick Jagger to celebrate the launch of her collection with Banana Republic on November 19, 2013.

The event, hosted at Chateau Marmont, Los Angeles, was reportedly the final time the couple – who met in 2001 – were pictured together at a public event.

L'Wren Scott was planning to close her business this week, a friend has revealed.

American fashion journalist Cathy Horyn said she was going to announce the end of LS Fashion today.

Cathy wrote in a piece titled Memories of a Friend, a Teacher and a Fighter, in the New York Times newspaper: "I sent her text on March 12, checking in. She didn't reply, but that wasn't unusual.

"I learned since her death that she was planning to close her business, with an announcement on Wednesday. Still, as painful as the decision must have been for her, I wouldn't draw any conclusions from it about her state of mind. Nor should any credence be given to reports of a breakup with Mick. It's rubbish."

Cathy is mourning the loss of the designer and she is devastated the world has lost a wonderful person, who she describes as a "vital, intelligent woman".

She explained: "She was with friends on Sunday night, and, yes, they were deeply concerned about her, but, no, they didn't think she would do something so desperate. Not L'Wren.

Her death is inexplicable to me, and it makes me angry, too. Angry because it's the loss of a vital, intelligent woman, and angry because, this once, I don't want her to be a mystery to me."

Tonight Ronnie Wood’s ex wife Jo, who knew L’Wren well, admitted her death may have been sparked by her perilous financial situation.

The 59-year-old told CNN: “Well, maybe, if anything the financial thing might have been the trigger, because she was such a proud woman that I think to to face that, well maybe that was the trigger.

"I don’t know, I’m surprised as much as everyone else.”

Talking about Mick’s state of mind, she added: “He’s devastated. He’s absolutely devastated, it must a real real shock for him”, before saying that she “never saw any kind of argument“ between Mick and L’Wren.

She admitted: “She was always very supportive of him. I think they had a nice relationship.”
